R min
= minimum allowed brake resistor that can be connected to the brake chopper
R max = maximum allowed brake resistor that allows P BRmax
P BRmax = maximum braking capacity of the drive, must exceed the desired braking power.
WARNING!
Do not use a brake resistor with a resistance below the minimum value
specified for the particular drive. The drive and the internal chopper are not
able to handle the overcurrent caused by the low resistance.

Parameter settings for external braking chopper and resistor

Disable the overvoltage control of the drive with parameter 30.30 Overvoltage
control.
Disable parameter 43.06 Braking chopper function as parameter group 43 Brake
chopper is used for internal braking chopper and resistor only.
